Bulk Grain

Bulk organic rye berries are the classic grain for making your own mushroom spawn. This is whole, triple-cleaned, USDA Certified Organic rye, sold in 20 lb bags or 2,000 lb pallets for growers who prepare grain in-house. Rye hydrates evenly, holds moisture without turning to mush when it's prepared right, and carries the carbohydrates and protein mycelium needs to colonize jars and bags quickly. Oyster, lion's mane, shiitake, reishi and most other gourmet species run well on it. OrganicUSDA...

Bulk white sorghum (milo) is triple-cleaned, USA-grown grain for making your own mushroom spawn, sold in 20 lb bags or 2,000 lb pallets. Milo's small kernels create more inoculation points than rye, and its tough hull keeps kernels whole through long sterilization cycles. The light color makes healthy mycelium and early contamination easy to see, and milo is an economical base for high-volume spawn production.

Bulk red sorghum (milo) is triple-cleaned, USA-grown grain for making your own mushroom spawn, sold in 20 lb bags or 2,000 lb pallets. Milo's small kernels create more inoculation points than rye, and its tough hull keeps kernels whole through long sterilization cycles. White mycelium stands out clearly against the red hulls, so it is easy to track colonization from day to day.

Bulk red millet is dry, untreated red proso millet for making your own grain spawn, sold in a 20 lb bag. Like white millet, its small kernels give mycelium far more inoculation points than larger grains for fast, even colonization. It is naturally high in protein and fiber and is grown on US farms using sustainable practices.

Bulk white millet is triple-cleaned, dehulled millet for making your own grain spawn, sold in 20 lb bags or 2,000 lb pallets. Its tiny kernels give mycelium far more places to start than larger grains, so jars and bags colonize quickly and evenly. Colonized millet also breaks apart into fine, evenly spread spawn, which makes it a favorite for grain-to-grain transfers and for spawning into bulk substrate.

Triple-cleaned, dehulled white millet for grain spawn, in a 40 lb bag. Millet's tiny kernels give you far more inoculation points per jar or bag than larger grains, so mycelium spreads quickly and evenly.
